ALEKSANDER TONEV will become Ronny Deila's third signing when he arrives at Celtic on loan from Aston Villa on Monday..
The Bulgarian winger will join Craig Gordon and Jo Inge Berget as the Norwegian manager's first recruits, with the club having the option to buy after the year-long loan.
And the Hoops are hoping to add at least one more player before Monday night's 11pm registration deadline for the Champions League play-off round.
Tonev was the subject of a £2million bid by the Hoops last summer.
But, after Celtic agreed a deal with his then club, Lech Poznan, in Poland, Aston Villa topped their offer by £500,000 and the 24-year-old chose to accept the chance to move to the Premier League.
Tonev struggled to make any impact as Paul Lambert's side fought relegation, failing to score a single goal, and is now looking to kick-start his career again at Celtic Park.
